About MRSA

Staphylococci or “staph” bacteria commonly live on the skin and in the nose. Usually, staph bacteria don’t cause any harm.

However,if they get inside the body they can cause an infection.

When common antibiotics don’t kill the staph bacteria, it means the bacteria have become resistant to those antibiotics.

This type of staph is called MRSA (Methicillin-Resistant Staphylococcus aureus).

MRSA was first identified in the 1960’s and was mainly found in hospitals and nursing homes.

In the late 1990’s, a new type of MRSA was identified.

This type of MRSA is becoming more common among children and adults who do not have medical conditions.

What does MRSA look like?

Most often, MRSA causes infections on the skin. These infections may look like any one of the following:

Large, red, painful bumps under the skin (called boils or abscesses)

A cut that is swollen, hot and filled with pus

Blisters filled with pus (called impetigo)

Sores that look and feel like spider bites (However, MRSA is not caused by a spider bite or any other insect bite.)

It is also possible to have MRSA in other areas of the body, such as blood, lungs, joints, eyes, and urine. These types of infections are less common, although they can be more serious. Because skin infections are the most common, this booklet will focus on them.

MRSA Transmission

How did I get MRSA?

Anyone can get MRSA. You can get MRSA by touching someone or something that has the bacteria on it and then touching your skin or your nose.

Some ways that you could get MRSA:

Touching the infected skin of someone who has MRSA

Using personal items of someone who has MRSA, such as towels, wash cloths, clothes or athletic equipment

Touching objects, such as public phones or door knobs, that have MRSA bacteria on the surface and then touching your nose or an open sore, paper cut, etc.

You frequently get cuts or scrapes on your skin (Your skin serves as a barrier to infection. When the skin gets damaged staph bacteria can enter and increase your risk for infection.)

There are two ways you can have MRSA.

You can have an active infection. An active infection means you have symptoms. This is usually a boil, a sore, or an infected cut that is red, swollen, or pus-filled.

You can be a carrier. If you are a carrier you do not have symptoms that you can see, but you still have MRSA bacteria living in your nose or on your skin. If you are a carrier, your doctor may say that you are colonized. These words - “carrier” and “colonized” - mean the same thing.

MRSA Diagnosis

Will I always have MRSA?

Many people with active infections are treated effectively, and no longer have MRSA.

However, sometimes MRSA goes away after treatment and comes back several times.

If MRSA infections keep coming back again and again, your doctor can help you figure out the reasons you keep getting them.

If I have MRSA, do I need to do anything special when I go to a clinic or hospital?

If you have ever had an active MRSA infection or you are a carrier, you should tell your health care providers.

They will wash their hands and wear gloves when caring for you.

They may also wear a gown over their clothes and may wear a mask.

If you are staying in a hospital or nursing home, a “Special Precautions” card may be put on the door of your room.

This card alerts staff to use extra care to prevent the spread of MRSA.

Your visitors may be instructed to avoid touching infected skin and to take other precautions such as wearing gloves or gowns when visiting you.

Is there a test for MRSA?

You would not usually be tested for MRSA unless you have an active infection. If you have a skin infection, your doctor may take a sample of the area to find out what bacteria is causing your infection. This is called taking a culture. The lab will then test the bacteria to find out which antibiotic is best for you. If your MRSA infections keep coming back again and again, your doctor may test you and your family members to see if you are carriers. In this case, the doctor would take a culture from the nose or other areas where MRSA can be found.

Treating MRSA

How is MRSA treated?

MRSA should always be treated by a doctor. It is important to follow the instructions for treatment that your doctor gives you.

If you have an active MRSA infection, your doctor may choose one or more of the following treatments:

MRSA is resistant to many antibiotics so it can be difficult to treat. However, there are antibiotics that can treat MRSA and make the infection go away. Your doctor may culture your infection and have the lab test the bacteria to find out which antibiotic is best for you. If your doctor gives you antibiotics, take them exactly as prescribed. Do not stop early, even if you feel better or if your infection looks healed. The last few pills kill the toughest germs. Never take antibiotics without a prescription from your doctor.

2. Drain the infection

Don’t do this yourself. It is very dangerous to squeeze or poke a skin infection because it can push the bacteria deeper into the skin and make the infection much worse. Your doctor will open the sore and drain it. After the infection is drained, you must keep it covered with a clean, dry bandage, until it heals

3. Reduce the amount of staph on your skin or in your nose

This may prevent the spread of MRSA if you have an active infection or if you are a carrier.

To decrease the amount of staph on your body your doctor may, for a short period of time:

Tell you to shower daily with antibacterial soap

Prescribe antibiotic ointment to put in your nose for several days

Prescribe antibiotic pills (in some cases)

Contact your doctor if:

you have any new symptoms during or after treatment for a MRSA skin infection such as a new fever or a fever that won’t go away

the infection gets worse

the infection is not healing

the infection comes back

you have questions

Preventing the Spread of MRSA

What can I do to prevent spreading my infection to others?

Clean your hands often with soap and water or an alcohol-based hand sanitizer

Take a bath or shower often, be sure to use soap to clean your body while showering or bathing

Wash your sheets and towels at least once a week

Change your clothes daily and wash them before wearing again

Do not share towels, wash cloths, razors, or other personal items

If you get a cut or scrape on your skin, clean it with soap and water and then cover it with a bandage

Do not touch sores; if you do touch a sore, clean your hands right away

Cover any infected sores with a bandage and clean your hands right away after putting on the bandage

Wear clothes that cover your bandages and sores, if possible

Clean frequently used areas of your home (bathrooms, countertops, etc.) daily with a household cleaner

Do not participate in contact sports until your sores have healed

Do not go to a public gym, sauna, hot tub or pool until sores have healed

Caring for Yourself

Does it matter how I wash my hands?

Yes. You have to rub your hands for at least 20 seconds to get rid of the bacteria.

How do I clean my hands with alcohol-based hand sanitizer?

Use enough to cover all the surfaces of your hands.

Clean Your Hands! PosterThis 11x17 poster shows the six steps for washing hands with soap and water or two for cleaning with alcohol-based hand sanitizers.

Laundry

Do I need to be careful when I do laundry?

Yes. Dirty clothes and bedding can spread MRSA bacteria.

When touching your laundry or changing your sheets, hold the dirty laundry away from your body and clothes to prevent bacteria from getting on your clothes

Wear disposable gloves to touch laundry that is soiled with body fluids, like drainage from a sore, urine or feces

Immediately put the laundry into the washer or into a plastic bag until it can be washed

Wash your laundry with warm or hot water, use bleach if possible

Dry in a warm or hot dryer and make sure the clothes are completely dry

Clean your hands after touching dirty sheets or clothing and before touching clean laundry, even if you have been wearing gloves

Throw gloves away after taking them off (do not reuse them) and clean your hands

How often should I change clothes and bedding?

Change your sheets and towels at least once a week

Change your clothes daily

Do not put dirty clothes or clothes you have just worn back in your closet or drawers until they have been washed

Cleaning

What about cleaning my house?

Use a household disinfectant or bleach solution to clean surfaces daily
